My wife is severely distraught over my incestual past.

My father died in a work accident 13 years ago. This was somewhat a blessing in disguise as he and my wife were at odds for most of our relationship. He was a cruel and bitter man who hated anything I did or anyone I associated with unless it was related to him. When I was a kid he made my life hell and I had to follow super strict rules for the majority of my childhood. If I disobeyed him, he would beat me up until I was too scared to move anymore, leaving me on the floor covered in blood and bruises.<br><br>After my father's death, I went through a period of mourning as anyone would do after losing a parent, but that didn't last very long. I blamed my father for my mother's death, as her death was related to her heart and it was heavily implied that it was caused by stress. He treated my mother like dirt while she did her best to keep the house running and provided for both of us. Even in death, he made a lot of trouble for people and a lot of people were relieved that he was gone and they didn't have to deal with him anymore.<br><br>His death also meant that I could finally open up about what he had done to me in the years before his death. It was very liberating, and I was able to live a much more fulfilling life after that. I met my wife a few years later and we have been really happy together for the most part. She was a bit surprised when I told her about my father, she was overwhelmed but she handled it really well.<br><br>It wasn't until I opened up about the "incest" I had with my sister when I was 13 that things took a turn for the worse. She got really upset, was close to tears, and lashed out at me for a while before running into our bedroom and closing the door behind her. I have tried to talk to her but she has been giving me the silent treatment and I'm not sure what to do. I don't know why she is reacting this way and it's scaring me, I don't want to lose her over this. I don't know what to do.<br><br>I was expecting her to be a little surprised and maybe even worried, but not this reaction. I thought telling her everything would bring us closer together but instead it is tearing us apart. This is an important part of my life that I can not and will never keep secret, no matter the cost.<br><br>I have been trying to tell her about me and my sister for a while, but I was too scared. She has a sister as well and they are very close and have a very healthy relationship and I have seen how joyful their relationship is. I was worried that she wouldn't understand, and I think I just proved myself right.<br><br>In context, what my sister and I did wasn't that crazy. We were both young teenagers who were going through puberty and were curious about sex. My sister was the one to initiate all of it, I was too scared to do anything. Looking back at it now, I should have stopped it long before it went as far as it did, but I did not and now she is in a lot of pain because of it. But it is what it is and it cannot be undone.<br><br>I love my wife more than anything and I don't know what I am going to do if she leaves me. Please help.
